安頓好了衣食住行的后,要準(zhǔn)備自己的工具。作為PLC的現(xiàn)場(chǎng)調(diào)試工程師,并不需要很多的調(diào)試工具。但是,一個(gè)螺絲刀、一臺(tái)萬(wàn)用表,還是*的。另外,如果要與現(xiàn)場(chǎng)的儀表傳感器進(jìn)行系統(tǒng)聯(lián)調(diào)的時(shí)候,還要有一臺(tái)信號(hào)發(fā)生器來(lái)模擬現(xiàn)場(chǎng)儀表的信號(hào),以確定當(dāng)發(fā)生問(wèn)題時(shí),現(xiàn)場(chǎng)的信號(hào)是完好的。還有,一臺(tái)結(jié)實(shí)的手提電腦,是你編程和調(diào)試的必需的工具。雖然這些工具你可以要求用戶準(zhǔn)備好,但是,作為一個(gè)職業(yè)的PLC工程師,如果連這幾樣工具都沒(méi)有,會(huì)被用戶懷疑你的職業(yè)水平的。其它的一些儀器儀表,如果需要的話,你可以向公司或者客戶提出來(lái),讓他們提前準(zhǔn)備,比如,示波器、穩(wěn)壓電源等等。畢竟這些不那么通用的儀器,通常是不可能隨身攜帶或備用的。

知識(shí)給人重量,成就給人光彩,大多數(shù)人只是看到了光彩,而不去稱量重量。 ?輸人輸出是PLC與外部設(shè)備進(jìn)行信息交流的通道,其是否正常工作,除了和輸入輸出單元有關(guān)外,還與聯(lián)接配線、接線端子、保險(xiǎn)絲等元件狀態(tài)有關(guān)。 出現(xiàn)輸入故障時(shí),首先檢查L(zhǎng)ED電源指示器是否響應(yīng)現(xiàn)場(chǎng)元件(如按鈕、行程開(kāi)關(guān)等)。如果輸入器件被激勵(lì)(即現(xiàn)場(chǎng)元件已動(dòng)作),而指示器不亮,則下一步就應(yīng)檢查輸入端子的端電壓是否達(dá)到正確的電
